Highlights

  • Rock chips returned up to 3.01% Cu from a newly mapped 180m structural zone at Chidna North.
  • The mineralised Aquila–Chidna corridor now extends beyond 4km, much of it untested by drilling.
  • Phase 2 drilling at Mt Oxide has passed 1,000m, targeting 4,000–6,000m by year-end.
  • A maiden Mineral Resource Estimate at Aquila is targeted for mid-2027.

True North Copper Limited (ASX:TNC) has reported high-grade rock chip results that extend the copper corridor at its 100%-owned Mt Oxide Project in Queensland. The results come as Phase 2 drilling advances at the Aquila and Vero prospects.

Chidna North Rock Chips Extend the Corridor

Rock-chip sampling at Chidna North returned up to 3.01% Cu from a newly mapped 180m structural zone about 2.5km north of Aquila. A second sample returned 2.38% Cu about 2km north of existing drilling.

The mineralised structure extends the Aquila–Chidna corridor beyond 4km, with much of it yet to be drill-tested. The area is associated with the Mount Gordon Fault Zone.

Phase 2 Drilling at Aquila and Vero

Phase 2 drilling has passed 1,000m, with the program targeting 4,000–6,000m across Aquila and Vero by year-end, subject to the wet season. Eight holes for about 3,110m are prioritised to test extensions 70–100m below existing intercepts at Aquila, with first assays due in December 2026.

Vero resource extension drilling begins in November, targeting high-grade extensions at depth and toward the Mara zone, about 300m along strike. Three holes for about 659m have also tested a 2.2km parallel geophysical trend west of Aquila at Apollo, with assays pending.

Geophysics and Upcoming Milestones

Queensland Government-supported UAV-SAM surveys are complete and additional ground-based IP work is underway, with interpretation and targeting results expected in November 2026.

Upcoming milestones include progressive assay releases from December 2026 to March 2027, 2027 drill planning in Q2 2027, a maiden Aquila Mineral Resource Estimate in mid-2027 and Vero development studies in H2 2027. The Mt Oxide Vero resource contains 220kt Cu, 5.13Moz Ag and 21.2kt Co.

Key Takeaways

  • New high-grade rock chips extend the Aquila–Chidna corridor beyond 4km.
  • Phase 2 drilling is underway, with first Aquila assays due in December 2026.
  • Geophysics results in November should help refine drill targets.
  • A maiden Aquila resource is targeted for mid-2027.
